About this map

The massive volcanic peak of Mt Shasta and its surrounding Mt Shasta National Landmark dominate the northeastern portion of this territory, where the Southern Pacific railroad follows the winding corridor of the upper Sacramento River. In the late 1970s, the landscape was a complex mosaic of industrial timberlands, protected wilderness areas like the Salmon-Trinity Alps Primitive Area, and small communities built around the rail and river systems.

Settlement patterns concentrate near the primary transit routes, from the lumber town of McCloud to the resort-adjacent Shasta Springs. Further west, the mountains reveal a legacy of extraction with scattered sites such as the Bonanza King Mine, Integral Mine, and Yellow Rose Mine. The map highlights the intersection of three counties—Siskiyou, Shasta, and Trinity—showing how rugged terrain like Castle Crags and the Scott Mountains shaped the development of northern California.
